GRAND RAPIDS, MI — Sewage and wastewater overflowing into the Grand River has prompted state and county officials have issued a no-contact advisory.

The advisory is in place until further notice, a news release from Kent County Health Department stated. Residents should use water conservatively until the flooding recedes.

If your well head is submerged in flood water, do not use the water for cooking, drinking, personal hygiene or other potable uses, the news release warned. After the floods recede, have water tested for contamination.

Sewage treatment plants are at capacity or overflowing after continued heavy rains. The sewage plant in Wyoming is spilling an estimated 1,000 gallons of partially-treated wastewater every minute, while the sewer system in Grand Rapids has overflowed some 200 million to 300 million gallons, according to reports. The Grandville treatment plant is also overflowing.

Treatment facilities were doing their best to keep with excess capacity, Adam London, acting Health Officer for the Kent County Health Department, stated in the release.

"The amount of sewage overflow is not just an environmental concern, but also a public health concern. Contact with the water could lead to illness in animals and humans," London stated.
